Extended Data Fig. 5: Minimal spanning tree (MST) analysis of the H I segments of the G165 VHVC.

Left and Middle panels: The MSTs of the density ridge points extracted by ClimbRidge in the 3D ppv cube (left) and on the 2D integrated intensity map of the G165 VHVC. Different colors represent different segments connecting every two neighboring nodes of the MSTs. Right panel: The PDFs of the segment lengths.
